Application filed; June 11,

The present invention appertains to new and useful improvements in waterheating systems and has forits primary object the provision of. heatingmeans of the class described adapted primarily for association with afurnace whereby the water contained within the; boiler thereof will beeliiciently heated. 7

Another object of the present invention is to provide a water heatingsystem of the class described including aplurality of heating coilsadapted to be positioned within the fire. box. of a furnace togetherwith new and novel connections between the coils and the boiler wherebya complete circulation of. water through the boiler and the coils willbe achieved.

Another object of the present invention is the provision of means.disposed in the connections. between the coils and the boiler wherebythe circulationofithe water through the coils and boiler may be stoppedshould the coils be broken or otherwise damaged.

Another object. of thepresent invention is to providemeans whereby thewater will be run directly into-the boiler during the time in which thecoils may be broken or are. being repaired; i J 7 1 Another object ofthe, present invention is the provision of a' water heating; system of Ithe class describedwhich consists of a mini- .mum number of parts, one:which is inexpensive to manufacture, efficient in its operation andwell-designed for the purposes for which it is intended. V

Numerous other objects and advantages of the present invention willbecome more readily apparent during the course of the followingdescription when taken in'connection with the accompanying drawings,

In the drawings forming a part of this application and wherein likecharacters of reference denote corresponding parts throughout theseveral views:

Figure. 1 is a side view, of one type of furnace showing the improvedheating system associated therewith.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a side view of one of the coils.

Reference now being had more particularly to the accompanying drawingswherein for the purpose of illustration has been disclosed a preferredembodiment of the pres- W'ATEB-HEATING SYSTEM.

out invention, the letter A generally repre- .sents a furnace of anyconventional orpreferred construction and B the present improved waterheating system associated therewith. I v v As stated above the furnace Amay be of any conventlonal or preferred construction so that adetalldescription thereof is not of furnace disclosed in theaccompanying drawings includes the fire boX 9 within which is arrangedthe fire grate lO'and above 11 111101 1 is disposed the boiler .11,thesebeing the parts of the furnace in connection with which the presentimproved water heating system is associated.

the forward ends thereof are connected'by means of the transverse pipe14 secured by one or more brackets 15 to the furnace directly beneaththe boiler. Secured: to the rear ends of the coils 12" and l3are theout.

let and inlet pipes 16' and 17' respectively, said inlet and outletpipes extending transversely' through and outwardly of the furnace asclearly shown in Figure '2. 5

Connected to the outer end of the outlet pipe 16 is the verticallydisposed pipe 18 having connected to its upper end the substantiallyhorizontal pipe 19 connected to the depending pipe 25 which leads intothe top of the boiler 11. Disposed within the horizontal pipe 19 is aone-way valve 20 operating only in the direction indicated by the arrowwhile an ordinary cut off valve 21 is thought to be necessary. However,the type i posite sides thereof and directly above the installed withinthe depending pipe 25 ad Carried by and communicating with the pipe 22is a by-pass pipe 26within which is installed a suitable cutoff valve27. Disposed within the length of the pipe22 are the two one-way valves28 and 29 operable only in the direction indicated by the arrows whilealso disposed within the length of said pipe 22 are suitable out-offvalves 30 and 31. p

The .freeflend oi? the pipe 22 is adapted to haveconnections withasuitable pump, not shown, which pump is adapted to force the waterthrough the coils into the boiler 11. In the normal operation of thepresent invention, such as when it is desired to circuelateithe, waterthrough the coils 12 and l3 :and boiler 11, the cut-off valve 31 isclosed i while the valves 27, 30, 21, and 24 are opened whereby thewater will be pumped through the bypass pipe '26 into, and through thecoils13xand 12 where it willbe heated after 'whichit will pass throughthe outlet pipe 16,.pipes 18, 19, and into the top of the boilerll. Thewater is then permitted to pass outw'ardly'of the boiler through thepipe 23 into the pipe 22 and thence to the coils from which it will passback into the lboiler in themanner set forth above. Thus, a completec1rculat1on of the water will at all times be achieved. The one-Wayvalve 28 will prevent the water from backing up in the pipe 22 while theone-wayvalve 20 will prevent thewater from backing up in .v the pipe 19;a 1 Should. the coils 12 and 13, for one reason or another, becomebroken or otherwise damaged so that they will not properly function,

the valves 27 and 21 are closed while the valves 31 and 24 are openedwith the result that the water will be caused to flow directly into theboiler 11. The valves 27 and 30 will prevent any water from reaching thecoils while the valve 21 will prevent the water from passing outwardlyof the boiler J through the depending pipe 25.' Thus, the

coils can be readily repaired after which the circulation of they watertherethrough can again be resumed in the forth above. 1

From'the foregoing, it will be appreciated that there has been provideda novel and simplified water heating system which will perform allof'the functions and accomplish allot the objects claimed and it is tobe further understood that while 'there'has been disclosed 'a preferredembodiment: of

manner set 1 the present invention, changes in the details pipeestablishing communication between one of the coils and the top of theboiler, a water supply pipe communicating'with the other coil, a controlpipe communicating with the bottom of the boilerandwith said supplypipe,'a' by-pass pipe around the point of juncture of the I control pipewith the supply pipe, a valve arranged in the supply pipe "beyondythe Yjuncture of the by-pass pipe. with the supply pipe, valves in theby-pass pipe and control pipe whereby upon manipulation water flow tothe 'coilsmay be out ofla nd' the water passed directly throughthecontrol pipe into the boiler.
